摘要： This electricity storage device is provided with an electrode assembly. The electrode assembly is constructed by laminating two electrodes of different polarities and a separator disposed between the electrodes with the electrodes being insulated from each other. Each of the electrodes has a metal foil and active material layers that are formed by coating an active material on the metal foil in a coating direction. The elongation rate of the separator varies in different directions, and the separator has a direction in which the elongation rate is higher than in the other directions. The higher elongation rate direction of the separator intersects the coating direction of the active material on at least one of the electrodes.

摘要： The stacked cell manufacturing method includes the steps of executing zigzag-folding of a band-like separator by the intermediary of a zigzag-folding mechanism, alternately feeding a positive-plate and a negative-plate onto the separator as folded back every time the separator is folded back by the zigzag-folding. A positive-plate transfer head and a negative-plate transfer head are set so as to alternately undergo a linearly reciprocating transfer in a horizontal direction at least on the table, the direction of a horizontal and reciprocating transfer made by the positive-plate transfer head and the negative-plate transfer head is set to coincide with a folding-back direction of the zigzag-folding of the separator, and a force caused by the horizontal and reciprocating transfer alternately made by each of these transfer heads is imparted to the separator guided onto the table, thereby executing the zigzag-folding while the separator is drawn onto the table.
